TIMING Application filed May 25,

To (4H whom it may concern:

Be it known that 1, JOHN M. ToRuENoE, a citizen of the United States, residing at 117 McDonough Street, Decatur, in the county of Dekalb and State of Georgia, have invented a new and useful Timing Device, of which the following is a specification.

This invention relates to a timing device whereby after the lapse of any predetermined period of time, an alarm. will be sounded, one of the objects of the invention being to provide a simple, compact and efiicient structure particularly designed for use in kitchens and by means of which several predetermined periods of time can be set and an alarm will be sounded successively upon the completion of each of said periods, the operation of said structure serving automatically to return the set parts to their normal positions after the signal has been operated. Y

With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed. it being understood that, within. the scope of what is claimed, changes in the precise embodiment of the invention shown can be made without departing from the spirit of the invention.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings c Figure 1 is a front elevation of the struc ture.

Referring to the figures by characters of reference 1 designates the casing in which the clock mechanism indicated generally as 2 is mounted, the same being insulated from the casing in any suitable manner, as by means of blocks 3. The arbor 4i driven by the clock mechanism extends into the central-portion of an opening 5 formed in one face of the casing 1 and secured to this, arbor and mounted for rotation in the opening is a disk 6 having an annular series of graduations at the margin thereof which can represent minutes or other periods of time. Extending radlally into the margin of the disk at each of the graduations there,-

on, is a recess 7 having a longitudinal slot 8 extending through one face of the disk. In each of these recesses 7 is slidably mounted a bolt 9 having a shoulder 10 projecting from its inner face and a spring 11 con nected to the bolt and to the inner end. wall of the recess and serves to hold the bolt normally retracted into the recess. A stem 12 projects from each bolt and slides with in the slot 8, said stem having a head 13.

A circular series of graduations, indicated at 14, are provided ,on the apertured face of the casing 1 and extend around the opening 5, these graduations'being adapted to register with the graduations on the disk 6 and certain of said graduationsjli being designated by numerals as shown, thus to indicate series of time.

Arranged within the casing 1 is a bracket 15 preferably insulated from the casing and having a stem 16 on which is mounted a lifting roller 17. This roller 'is located adjacent the zero (0) graduation on the casing 1 and is electrically connected to a bell 18 or other signal, a battery 19 or other source of electrical energy. and to the clock mechanism 2.

It is tobe understood that under ordinary conditions all of the bolts 9 are retracted into their recesses 7 so that the disk 6 can thus rotate freely without causing the signal 18 to be operated. Should it be desired to have the signal operated after an interval of fifteen minutes, the operators press outwardly and inwardly upon the head 18 registering with the graduation l l designated by the numeral 15 on casing 1. Thus the bolt 9 controlled by said head 13 will be shifted radially and inwardly so that its shoulder 10 will engage the edge of the disk 6. This will hold the spring 11 under tension with the bolt 9 projecting beyond the periphery of the disk. After the completion of fifteen minutes this projecting portion of the bolt 9 will be brought into position to ride on the roller 17. Thus it will be shifted so as to disengage the shoulder 10 from the disk 6 and allow the spring 11 to retract the bolt 9 into the recess 7. As long as'the bolt 9 is in contact with the roller 17 a circuit will be completed to the alarm 18 which will be sounded until the bolt has been retracted away from the roller 17. Obviously several of these bolts may be projected at different distances from the zero graduation and they
